Trading Multi Symbols

Can MC set up a strategy scanning for some criteria of say 500 symbols and automatically pick one of those for trade? i read that market scanner can only set up an indicator for single symbol but cannot export their results to EL. And to set up a chart it seems can only allow 50 data (multi-data(n)). So, will there be a way that i can run a strategy for a large number of symbol without even create a chart?

I am looking for a real good solutions for real time portfolio trading. Can any one give me suggestion whether MC can do it or i need to consider Ninjatrader in future?

many thanks
GM
